<em><u>How to determine the min hull dimensions of a catamaran</u></em>
Lenght/beam ratio
<h3> catamaran-LBRC</h3><h3> LBRC = LH/Bcb</h3><h3>if we set Lbrc = 2.2 the longitudinal and tranversal stability will come very near to the same value. we can design a sailing cataraman wider or narrower , if we like wider contsruction makes its heavier , narrower means that it will carries less sails.</h3>
Answer:
3. they can travel through solids
4. they move rock at right angles to the direction of wave travel
Explanation:
- S waves are called transverse waves they have the ability to move past the solids. They cannot move through the liquids, these waves are perpendicular to the direction of travel.
- They are also called longitudinal waves, the ad is second to record on the seismograph as they slowly pass through the rocks. They have a speed of 3.4 to 7.2 km as per the boundary.
Answer:
b. 3 times
Explanation:
Lets take
Coefficient for ordinary glass = α₁
Coefficient for pyrex glass = α₂
Given that α₁ = 3 α₂
Initial length of both glasses are equal = L
Change in the temperature is also same .= ΔT
We know that change in the length given as
ΔL = L α ΔT
Therefore
ΔL₁ = 3ΔL₂
Therefore change in the length of original glass is three time of pyrex glass.
b. 3 times
